Bank Schweiz AG late last year became Switzerland’s first bank to
comprehensively pass along negative rates to all of its customers.
Violating an almost religious precept in the financial world, ABS
informed its clients that they would have to pay a charge of at least
0.125% to maintain their accounts at the bank starting in 2016.

In
January, as the titans of global finance gathered in Davos, ABS Chief
Executive Martin Rohner was poring over data in his bank’s Zurich office
near a gritty red-light district and sounding cautiously hopeful. In
the first two full months after ABS’s October negative-rate
announcement, 1,797 clients had left the bank, but 1,830 new accounts
had been opened—for a net gain of 33.

“We had an excellent year,” Mr. Rohner said at the time.

data for January and February, the most recent available, showed that
ABS was still net positive on accounts, with its gain expanded to 59.

Pietro Majno, an ABS client, said he never considered leaving after
the bank started charging him to hold his money. A professor of surgery
at University Hospitals of Geneva, Dr. Majno said he thinks ABS is more
transparent and reliable than other banks. “Maximizing profit is not my
aim,” he said.

ABS’s decision is providing a real-life data point
for a question that has bedeviled economists: what happens when
negative rates are passed on broadly to consumers? In theory, they
should prompt people to spend their money or hoard it in cash under a
mattress, rather than save it at a bank and watch it shrink. But there’s
little evidence of how people might in fact react.

At ABS,
total account balances fell by 4%, or 54 million Swiss francs ($56.5
million), between last October’s negative-rate announcement and
February, as clients shifted money from cash holdings at the bank into
investments. However, overall assets under management remained steady,
